In preparation for external device tree support where device trees are not build from a kernel recipe, factor out the qcom boot image creation into a function and call that for every kernel devicetree. No functional changes. Signed-off-by: Rouven Czerwinski <rouven.czerwinski@linaro.org> (cherry picked from commit 99475a5)
Add support for device trees that are not build from the kernel
repository. The implementation is similar to kernel-fit-image.bbclass,
we detect whether the provider for virtual/dtb has been changed and
retrieve the build devicetrees from the sysroot instead of using those
build by the kernel.
A new variable QCOM_BOOTIMG_DEVICETREE is introduced to specify the
trees for which boot images should be build.
In order to use this, set the provider for virtual/dtb to your device
tree yocto recipe and then specify QCOM_BOOTIMG_DEVICETREE:
PREFERRED_PROVIDER_virtual/dtb = "my-devicetree-recipe"
QCOM_BOOTIMG_DEVICETREE ?= " \
my-devicetree-for-bootimg.dtb \
"
in your machine configuration.

(cherry picked from commit 2c16f58)
Name boot images generated from external dtbs with a -ext-dtb suffix to indicate that they were generated from an external device tree recipe and also to prevent overwriting similarly named boot images generated from a kernel device tree. Signed-off-by: Rouven Czerwinski <rouven.czerwinski@linaro.org> (cherry picked from commit e4c5f6c)
Add a devicetree-dummy recipe that generates an empty but valid DTB for testing with the qcom-armv8 machine. Signed-off-by: Rouven Czerwinski <rouven.czerwinski@linaro.org> (cherry picked from commit 7580c30)
Modify the qcom-armv8 machine to use the dummy device tree recipe and generate a boot image from an external devicetree with it. Signed-off-by: Rouven Czerwinski <rouven.czerwinski@linaro.org> (cherry picked from commit aa00cff)
